Title: Card transaction settlement method in point of sale systems
Inventor: KIM KANG HYOUNG
IPC: G07F7/12
Filed: 1998-09-09
Abstract: The present invention is related to a card transaction settlement method of a point of sale system, POS system, and more particularly to the card transaction settlement method in which a payment by either the credit card or the debit card is made after an approval before the card transaction for the virtual transaction amount is given, and in which when the transaction is completed, an approval after the card transaction for the actual transaction amount is requested for the transaction settlement whereby the settlement with the cards can be conveniently accomplished since conflict between the merchant and the consumer, caused by such as the difference between the transaction amount and the debited amount against the card, can be eliminated, and whereby the merchant has less of the financial risk for refund, and whereby the signature is not necessary in the signature form, resulting in that true non-cashier self-service sales can be introduced to the sales management system.
Patent CA-2247568-A1 (CA)
Title: Implants with bone in-growth surface and process therefor
Inventor: ARCHBOLD JEFF DAVID
IPC: B23K26/402
Filed: 1998-09-15
Abstract: A process to produce a bone in-growth surface is described. Bone tissue grows into the in-growth surface of the implanted prostheses to anchor the artificial joint mechanically. The process machines the macroscopic surface of the prosthetic implant by, inter alia, wire-electrodischarge machining, waterjet cutting, laser machining, such that channels at least 50µm in size and up to, but not limited to, 3mm in size are created tangentially to the surface. These channels contain undercut regions which provide excellent long-term fixation of the implant in bone tissue. The machining process creates a micro-roughness on the microscopic surface of the channels which enhances early in-growth of bone tissue, reducing healing time.  The process to create the bone in-growth surface does not compromise the use of Morse's Taper to improve initial fixation. The in-growth channels formed by the process reduce failure of implants by crack propagation fatigue through a diminution of stress concentration regions. The invention is applicable to various configurations of prostheses.

Patent CA-2251504-A1 (CA)
Title: Feedforward amplifier with improved characteristics without using pilot signal
Inventor: SENDA HARUYASU
IPC: H03F1/32
Filed: 1998-10-26
Abstract: A feedforward amplifier which includes a distortion detector, a distortion eliminator, an error power extractor, a first level detector and a first controller.          The error power extractor extracts output error power due to variations in the distortion eliminator by combining the output signal from the distortion eliminator with the signal from a first linear signal path in the distortion detector in opposite phases.  The first level detector detects the output error power extracted by the error power extractor, and the first controller controls a first variable attenuator and a first phase shifter which are interposed in the distortion eliminator such that the output error power is maintained at zero.  This can solve a problem of a conventional feedforward amplifier in that the power level of the pilot signal must be increased to heighten the detection sensitivity of the pilot signal because the detection level of the pilot signal becomes minimum at an optimum operation point, and that the increasing power of the pilot signal degrades the communication quality of a system employing the conventional feedforward amplifier.

Inventor: MINTCHEV MARTIN P
IPC: A61N1/36
Filed: 1997-09-04
Abstract: A device and method for electrical stimulation of a portion of the gastro-intestinal tract, defining a longitudinal axis. A proximal and at least one distal electrode set are arranged circumferentially about the portion of the gastro-intestinal tract in a plane substantially perpendicular to the longitudinal axis and in axially spaced relationship relative to each other.  At least one power source provides an electrical stimulus to the electrode sets sufficient to stimulate the smooth muscle to produce a local circumferential contraction at each electrode set. A timing mechanism phase locks the electrical stimulus such that it is applied to the electrode sets successsively and repetitively. The axially spaced relationship between the electrode sets and the timing of the electrical stimulus are selected such that the local circumferential contractions are artificially propagated distally through the portion of the gastro-intestinal tract.

Abstract: A stereo camera which decreases loss of picture caused by the disagreement of photographing ranges between the right and left lenses. The distance P1 between the optical axes of the right and left photographing lenses 10R, 10L is set to be nearly midway between a distance P1max between the optical axes at which the photographing ranges of the right and left photographing lenses come into agreement with each other at an infinite point and a distance P1max between the optical axes at which the photographing ranges of the right and left photographing lenses come into agreement with each other at the shortest photographing distance.

IPC: B02C17/22
Filed: 1999-07-14
Abstract: A segmented liner assembly and liner segment fastening system is disclosed for the rotatable shell of an ore grinding machine, the shell having a plurality of mounting bores formed therethrough. The liner assembly consists of a plurality of liner segments each of which has one mounting bore that extends into the body of the segment from its mounting surface and a mounting recess having a transverse size greater than that of the mounting bore which extends from the mounting bore to the grinding surface.  A threaded member extends through a mounting bore of the shell and an aligned mounting bore of the segment into the recess of the segment and externally of the shell. The threaded member is screwed into a nut that is seated at the base of the mounting recess. In a first embodiment, the treaded member has an integrally formed wrenching head enabling the threaded member to be rotated and screwed into the nut, thus drawing the liner segment tightly against the inner surface of the shell. In a second embodiment, rather than a wrenching head, a second nut is used externally of the shell and the end of the threaded member has a smaller wrenching portion. In either case, when removal of the liner assembly is necessary for replacement, the threaded member is reverse rotated to remove it from the internal nut, enabling the liner segment to be removed.
